Enhancement of MT effect and/or CEST effect

摘要

A magnetic resonance imaging (MRI) system, method and/or computer readable storage medium is configured to effect enhanced magnetic transfer (MT) effects and chemical exchange saturation transfer (CEST) effects. The configured techniques include irradiating an object in an MRI gantry by applying a sequence of magnetic transfer (MT) pulses over a range of different frequencies, and then applying an MR imaging sequence to the irradiated object.

1. A magnetic resonance imaging (MRI) system comprising:
an MRI gantry including a static magnetic field coil, gradient magnetic field coils, at least one radio frequency (RF) coil configured to transmit RF nuclear magnetic resonance (NMR) RF excitation pulses into an imaging volume, and to receive NMR spin echo RF signals from an object located in the imaging volume; and control circuits configured to control gradient magnetic fields generated by said gradient magnetic field coils, and to transmit/receive RF signals to and from said at least one RF coil, the control circuits being configured to perform operations comprising:
applying to the imaging volume a sequence of magnetic transfer (MT) RF pulses including at least two different MT frequencies;thereafter applying at least one MR imaging sequence to the imaging volume; andreceiving NMR spin echo RF responses from said at least one RF coil.
